Caption: Typhoon fighter plane cockpit screen display. This is a simulation of a multiple-display screen. The option buttons around the screen allow different data to be displayed. Here, a navigation map is overlaid with the aircraft position (green, lower centre) and readings from radar and other sensors. The Eurofighter Typhoon, developed as the most advanced fighter jet in the world, is flown by a computerised flight control system. A range of simulators were extensively used to design and test the jet. The Eurofighter is a joint project between the UK, Germany, Italy, and Spain. The Eurofighter Typhoon will enter service in 2003.
